Man's Best Friend Sniffing out Iron Ore Deposits

See video

I was watching BNN  today Tueday June 5 with Pamela Ritchie hosting the Commodities Show and came across a story about a company using dogs to successfully sniff out iron and copper. I did a little searching and came across this video. Forget about using expensive new high tech to find deposits.Your dog Fido has the goods.  www.youtube.com/watch?v=TlXl10ERH6I
